GÜNEYDOGU ANADOLU BÖLGESİ'NDE DAGILIŞ GÖSTEREN TATLISU SALYAN GOZU Bithynia tentaeu/ata (L., 1758) (GASTROPODA: PROSOBRANCBIA)'NIN YAG ASİTİ İÇERİGİ

Bu çalışmada, Nisan 2007 tarihinde Mardin ilinin Sultanköy Köyü'nden toplanan tatlısu salyangozu Bithyniatentaculata'nın total vücut lipitleri, ince tabaka kromatografi ile fraksiyonlandı. Salyangozun, total vücut lipitleriile fosfolipit ve nötral lipit fraksiyonundaki yağ asitleri, gaz kromatografi ve gaz kromatografi-kütlespektrometresi (GC-MS) ile analizlendi. Analizlerde, doymuş yağ asitlerinden C1 2:0, C1 4 :0, C1 5 :0, Cl6:0,Cl 7:0, C18:0; tekli doymamış yağ asitlerinden C16:1ro 7, C18:1co9, C20:1co9 ve çoklu doymamış yağ asitlerindenCl8:2ro6, C18:3ro3, C20:2ro6, C20:4ro6 ve C20:5ro3 asitler saptandı. Tek karbonlu ve 20 karbonlu çokludoymamış yağ asitlerinin yapılan, gaz kromatografı-kütle spektrometre ile doğrulandı. Lipit fraksiyonlan arasındabu bileşenlerin yüzde değerleri karşılaştınldı. Yüzde dağılımda en çok C16:0, Cl6:lco 7, C18:1co9, Cl8:3ro 3 veC20:4co6 asitler tespit edildi. Fosfolipit, nötral lipit ve total lipit yüzde içeriğinde bazı farklılıklar tespit edildi.örneğin, total doymuş yağ asiti yüzdesi (o/o4 5.1) ile total tekli doymamış yağ asiti yüzdesi (% 28.0) en fazlanötral lipitte; total çoklu doymamış yağ asiti yüzdesi (o/o46.5) ise en çok fosfotipİtte saptandı. Eikosanoidlerinöncül maddesi olan C20:4ro6 ve C20:5ro3 asitlerin yüzde oranlan nötral ve total lipit analizlerine göre fosfolipitfraksiyonunda daha fazla bulundu.
